BARREL-MAKING MACHINE.

Application filed April 2,

My invention relates to a barrel making machine, and has particular reference to a rotatable barrel holding member, for use in nailing. the wooden hoops of the barrel.

In accordance with my invention, I provide a machine of the above mentioned character including a rotatable barrel holding member, preferably embodying a plurality of expansible drums. The barrel is arranged upon the supporting member and the drums are arranged within the barrel beneath the intermediate wooden. hoops which are to be nailed upon the barrel. Each drum embodies a plurality of expansible sections, whereby the barrel may be properly expanded and held in the expanded position during the nailing operation. The eXpansible sections permanently overlap, whereby the nails can not possible'be driven between the sections and invariably have their inner ends clinched. Means are provided to readily expand and contract the drums. The entire device is of simple construction, and easy to operate, by unskilled labor.

In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of the machine embodying my invention,

Figure 2 is a transverse section taken on line 22 of Figure 1,

Figure 3 is a horizontal section taken on line 33 of Figure 1,

Figure 4c is an end elevation of the rotatable barrel holding member,

Figure 5 is a side elevation of the spider included in each of the expansible drums,

Figure 6 is a central vertical longitudinal section through the barrel holding member shown in Figure 4,

Figure 7 is a transverse section taken on line 7-7 of Figure 6, and,

Figure 8 is a perspective View of one of the expansible segments included in the drum.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 10 designates a vertical standard, carried by a base 11. At its upper end, the standard 10 is provided with a horizontal bearing 12. The numeral 13 designates a companion vertical standard, upon the upper end of which is bolted or rigidly attached a U-shaped hearing member 14, having knuckles or bearings 1928. Serial No. 266,698.

15, as shown. Formed integral with the outer bearing or knuckle 15 are horizontal knuckles 16, spaced as shown.

Rotatably mounted within the bearings 12 and 15, is a horizontal tubular drive shaft 17, of relatively large diameter. This drive shaft is rotatable but incapable of partaking of longitudinal movement. The drive shaftis rotated at a suitably slow speed by means of a large wheel 18, rigidly secured thereto, and driven by a belt 19.

Rigidly mounted upon the tubular shaft 17 is a head or drum 20, which is noneXpansible and the periphery of which is preferably tapered, as shown, for receiving thereon the opened end of the barrel.

The rotatable barrel holding member further comprises a plurality of expansible drums 21, two being shown for the purpose of illustration. These drums are identical and a description of one will suflice for both. Each drum embodies a spider 22, including a hub 23, and radial arms 24., integral therewith. The hub is rigidly mounted upon the tubular shaft 17 by means of a clamping bolt 25, or the like, as clearly shown in Figure 6. The arms 24, Figure 7, are provided with T-shaped longitudinal grooves 26, slidably receiving T-shaped ribs 27, formed integral with the radial arms 28. Formed integral with the outer ends of these radial arms are segments 29, constituting the periphery of the drum. These segments are permanently spaced so that they may partake of true radial movements.

The segments 29 are transversely inclined, to conform to the longitudinal curvature of the barrel, and are provided at their lower ends with radial ribs or flanges 30, to engage the shoes 31. These shoes have their ends tapered, and permanently overlap, when the drum is contracted or expanded. By having the shoes overlap, it is impossible for the operator to drive a nail between the shoes, whereby the inner ends of the nails will al ways he clinched.

slidably contacting with the periphery of the tubular shaft 17 are longitudinal shifting rods 32, slidable within openings or notches 33, formed in the hubs 23. The arms 28 are provided at their inner ends with notches 33, to receive the rods 32, when the arms are in the inner contracted position. Pivotally connected with the longitudinal rods 32, as shown at 34:, are expanding links 35, the outer ends of which are arranged between knuckles 36 and are pivoted thereto, as shown at 37.

Pivotally connected with the outer fre ends of the rods 32, as shown at 38, is a head 39, with which is rigidly connected an operating rod it). The tubular shaft 17 has a much larger diameter than the operating rod 40, and this operating rod is sufliciently flexible so that it may partake of slight lateral movement, but is suitably stiff for shifting the head 39 in opposite directions.

The numeral 11 designates a cylinder, having its upper portion rotatable within the opening 42, formed in the upper knuckle The cylinder is provided at its top with an enlarged head i3, to prevent downward displacement of the cylinder. At its lower end, the cylinder has a trunnion l-i, rotatable within the opening if) of the lower knuckle. The head 43 has a radial opening to receive a handle 46, to turn the same. The cylinder is: is provided with a horizontal opening or passage extending throughout the major portion of its area, and adapted to receive an eye 4-8, formed upon the rod it). This eye is pivoted to the cylinder, near the periphery of the cylinder by a bolt 4:9, or the like.

The operation of the machine as follows:

The drums 21 being in the collapsed condition, the barrel is placed over them with its top or open end engaging the drum 20. The lever 46 is now turned clockwise, rotating the cylinder 41 and drawing the operating rod 10 to the left. This shifts the head 39 to the left and the links 35 are moved radially, in turn shifting the arms 28 radially. The segments 29 are expanded and are locked beneath the intern'iediate wooden hoops of the barrel. The shaft 17 is slowly rotated, and the oper ator standing upon one side of the barrel, drives the nails into the hoops and barrel, the inner ends of the nails being clenched by engaging with the shoe. 7

To remove the barrel, the lever 46 is swung in a reverse direction, and the drums are contracted, whereby the barrel may be removed.

It is to be understood that the form of my invention, herewith shown and described, is to be taken as a preferred example of the same, and that Various changes in the shape, size and arrangementof parts may be re- ,sorted to without departing from the. spirit of my invention, or the scope of the subjoined claim.

Taving thus described claim A barrel making machine for use in nailing hoops to the body portion of the barrel, comprising a support, a substantially horizontal tubular shaft rotatably mounted upon the support, expansible drums carried by the tubular shaft, each drum embodying a spider having a hub and radial arms, said hub having a central opening to receive the tubular shaft, and radial slots leading into the central opening, said radial arms having longitudinal grooves, each hub being rigidly attached to the tubular shaft, radial reciprocatory arms mounted to slide upon the radial arms of each spider and having ribs provided with interlocking slidable engagement within the longitudinal grooves of the spider arms, segments carried by the outer ends of the radially reciprocatory arms and disposed in a circular group and partaking of true radial movements and being in circumferential alignment when shifted to the extreme inner and outer positions, shoes attached to the outer faces of the segments and having their ends projecting beyond the corresponding ends of the segments, the projecting ends of the shoes being tapered and permanently overlapping when the shoes are shifted to the extreme inner and outer positions whereby a nail can not be driven inwardly past the shoes, reciprocatory rods slidably contacting with the outer surface of the tubular shaft and slidably mounted. within the slots in the hubs ot the spiders, angularly arranged links pivotally connected with the rods and with the outer ends of the radially reciprocatory arms, the longitudinal movement of the rods in one direction serving to shift the links to simultaneously slide all of the radially reci roe-atory arms outwardly while the side thrust of the rods is taken by the tubular shaft, an operating shaft extending within the tubular shaft, a block connected with the ends 01 the rods and with the adjacent end of the shaft, and means to move the rod longitudinally with relation to the tubular shaft.

In testimony whereof I aliix my signature.

my invention, I
